Abstract

Soil cultivation tool for a tillage tine, preferably cultivator tines, which is tapered at the lower end of the tine handle for frictionally and positively receiving the share and the guide plate, the guide plate tapering at the lower end and the share on the receiving shaft in the working direction or towards the share tip and that the lower end of the tine handle with the receiving shaft of the coulter has an aligned opening for receiving a securing element that can be released without tools and lateral protection shaft extensions are arranged on the receiving shaft to protect the securing element and the lower end of the tine handle has a tine handle nose as loss and / or anti-twist protection.

Description

The The invention relates to a tillage tool, in particular for a Cultivator, with the features according to the preamble of the claim 1.

In WO 01/24603 is, for example, such a tillage tool described. The coulter attachment described there at the lower end of the tine handle by means of positive and frictional engagement proven in terms of interchangeability and security against loss.

At the Changing the coulter is, however, to press in the securing element a special tool is required. The stroke of the securing element can be limited by dust and corrosion. Changing the coulter is then only possible with additional effort.

The Invention is based on the object for a form and friction on one Tine handle attached tillage tool a simple Loss protection to create a tool-free protection of the share.

According to the Task solved by that the Shank of the coulter on the side of the shank extensions has the side over the stalk and over the securing means protrude and / or is below the tine handle of the breakthrough arranged a nose that serves as an anti-rotation device for the Belay means is designed and to protect the belay means backwards over the security means protrudes. Through these protective shank extensions and / or the tine handle nose is the uncontrolled release of the securing means during the Avoided work.

The Shank extensions can be easily done without additional operations and train them to save material. The tine handle nose can be by changing the contour arrange in a simple manner at the end of the tine handle.

Further Advantages and features of the invention emerge from the subclaims as well the sample descriptions and the drawings. It shows:

1 a tillage tool with share and tine handle in side view and in section

2 a tillage tool with a double heart share and tine handle in side view and in section

3 a tillage tool in section AA

4 a tillage tool with screw-on coulter receiving wedge in side view and in section

5 a tillage tool in section BB

6 a lower tine handle end with tine handle nose and securing element with linch pin in view "X"

7 a lower tine handle end with tine handle nose and securing element with spring pin in view "X"

The 1 shows an inventive tillage tool 3 with a tine handle 2 for a cultivator, not shown. The attachment of the tine handle 2 on the cultivator frame is not shown. The tillage tine 1 shows the tine handle 2 with the molded coulter wedge 18 , the molded tine handle nose 11 and the breakthrough 13 on. That on the share wedge 18 arranged tillage tool 3 shows a gaggle 4 with a working direction 7 pointing share point 6 on and a receiving shaft 5 with shank extensions 10 and a breakthrough 13 for the securing element 9 , This breakthrough 13 has in the receiving shaft 5 a larger cross section for tolerance compensation. Above the coulter shaft 5 is preferably a baffle 12 arranged. The securing element 9 has a safeguard 15 on, the securing means 15 an captive part of the securing element 9 can be.

The 2 shows another example of a tillage tool according to the invention 3 , in which the same parts are provided with the same reference numerals. The embodiment differs from that in FIG 1 shown embodiment in that a double heart family 19 with 2 share points 6 is shown. This double heart group 19 is after wear of the lower share tip 6 usable by turning 180 ° around axis of symmetry II.

The section AA in 3 represents the receiving shaft 5 with shank extensions 10 and the aligned breakthroughs 13 and the lower end of the tine handle 8th with the molded coulter wedge 18 and the securing element 9 with securing means 15 ,

For lower tine handle ends 8th without molded coulter wedge 18 it is conceivable to use a preferably screwable share receiving wedge 18 for holding the tillage tool 3 to arrange as in 4 is shown. To protect against loss of the securing means 15 is preferably a protective block 20 arranged. The frictional and form-fitting connection of the receiving shaft 5 and the coulter receiving wedge, which is not formed in one piece 18 is in 5 shown.

The 6 shows a securing means according to the invention in view "X" 15 to the securing element 9 in the form of a linch pin 16 with an anti-rotation device 14 on the tine handle nose 11 ,

It is also possible, as in 7 shown, the securing element 9 with a spring pin 18 secure against loss and / or twisting.

Should the tillage tool 3 get a blow from the back while working, so the securing element 9 sure the shank 5 not from the wedge 18 slips. The shank extensions 10 and the tine-stem nose 11 prevent when setting or pulling in the tillage tool 3 in the ground that the securing means 15 uncontrolled by the security element 9 solves. Through the anti-twist device 14 the wear is caused by automatic turning of the safety element 9 reduced.
